This
unit is the liquid and steam are directly mixed, and the
liquid is heated.Inside
the heater is the condensation nozzle which is drilled
to allow the steam topass
into the liquid. The heating steam thus makes direct contact
with the liquid.

-
There is almost no vibration or noise due to condensation
of steam-
Since liquid and steam are mixed, directly thermal efficiency
is high and thers'slittle
heatloss.-
Controlling liquid temperature is easy, and the steam
consumption can be econonized.
